CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 258,343, dated May 23,lese.

Application filed April 7, 1881. (Model.)

To all whom t may concern Be it known that I, CHARLES 0. ALLEN, ot'Grand Rapids, in the county of Kent and State of Michigan, have inventeda new and Improved Rotary Brush; and I do hereby declare that thefollowing is afull, clear, and exact description ofthe same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure is a side view ot the brush, partly insection. `1"ig. 2 is afsimilar view, showing a modified form ofthe-'same My invention relates to an improvement in rotary brushes,designed more particularly for carpet-sweepers, but applicable also forother uses.

It consists of a brush formed of a central core having sockets boredtransversely therein from opposite sides, and connected by smallerholes, in combination withbristlesand wires wrapped around the middle ofthe tufts of bristles and drawn into the socket, the said smallercommunicating holes affording a past sage-way for the wires and fordrawing the1 bristles in. l

It also consists in the peculiar manner ot` 'connectin g the bristlesockets by diagonal 1 holes, whereby only one wire may be used,` andthat entirely concealed within the brushcore, as hereinafter more fullydescribed.

In the drawings, B represents the central` wooden core, which hasbristle-sockets bored` therein from opposite sides till the holes nearlymeet, leaving a small hole, c, formed prefer-U ably by the worm of thebit when the holes` are bored in a diametrieal line, which hole"connects the two opposite bristle-sockets to form a continuous holethrough the core." Tufts of bristles a are then caught by looping twowires, b b, around their middle parts, and the bristles are then drawninto the sockets from the opposite sides, while the wires pass Vthroughthe small hole c in the middle. The

free ends of the wires are then laced through the next pair of socketsand communicating hole, and a second set of bristles are then drawn inby the same method. a

As a modification of my brush, I may construct it as shown in Fig. 2,which has the advantage of requiring but one wire to fasten thebristles, and also of perfectly concealing the wire. Thus, instead ofreturning the wire through the small hole c, effecting communicationbetween the diamctrical sockets, I

form a second set of diagonal holes, d', which AI prefer to use fourrows of bristle-sockets arranged in the forni of spirals, and the wireis first secured at one end ot' the core and' laced through two oppositesets of bristlesockets, and is then returned through the other two setsot' sockets that lie in a plane at right angles to the first, the wirebeing then fast-A ened at the same end ofthe core where it was entered.

The construction ot'wbrush herein described saves allarge amount ofstock, holds the bristles very strongly, and it is cheaply and substantially made.

Having thus described my invention, what I claim as new is- 1. A rotarybrush consisting of a central core havingbristle-sockets bored thereintransversely, with smaller holes or passage-ways connecting thesesockets, in combination with The same wire I he bristles and one or morewires laced through said holes and around the middle ot' the tufts ofbristles, as described.

2. A rotary brush consisting of a central core having bristle-socketsbored therein trans- Witnesses:
